ROBERT D. SPECK, OF ROCKFORD, WASHINGTON.

VETERINARY DENTAL HALTER.

To all whom it may concern.

Be it known that 1, ROBERT D. SPEOK, a citizen of the United States,residing at Rockford, in the county of Spokane and State of WVashington,have invented certain new and useful Improvements in Veterinary DentalHalters, of which the following is a specification.

This invention relates to a veterinary dental halter.

The primary object of this invention is to provide a halter of thischaracter by means of which the head of the horse, or other animal, maybe firmly held in any desired position during the operation of anydental work.

With the foregoing and other objects in view, the invention consists inthe novel features of construction, combination and arrangement of partsillustrated in the drawings and more particularly pointed out in theappended claims.

In the accompanying drawings :Figure 1. is a perspective view,illustrating the application of the halter. Fig. 2. is an elevation ofthe bands, and Fig. 3 a plan view of Fig. 2.

Referring to the drawings for a more particular description of theinvention, and which drawings are for illustrative purposes only and aretherefore not drawn to scale, the device comprises the nasal band 1,consisting of a flat strap of steel bent into the requisite form andprovided on its inner surface with a lining of leather 2, or othersuitable material conforming to the shape of the face. The devicefurther comprises a second band 3, adapted to fit the lower jaw of theanimal near the fifth molar, also provided on its inner surface with alining 4:, of leather or other suitable material.

5 indicates the leather throat latch of the device, 6, the loop chinpiece, and 7 the forehead strap. The ends of the bands 1 and 3 areprovided with the outwardly bent extensions 8 and 9, respectively,through which pass the connecting bolts 10, provided at their lower endswith the thumb screws 11. Coil springs 12 are disposed around theconnecting bolts between the ex tensions 8 and 9, the tendency of whichis to spread apart or expand the sections 1 and 3.

In practice, the bands 1 and 3 may be easily slipped into position andthen adjusted to the animals head by the thumb Specification of LettersPatent.

screws 11. To remove the bands from the animals head, it is onlynecessary to partially unscrew the thumb nuts 11 when the bands areslightly separated by the coil springs 12 and may be slipped off.

From the foregoing description taken in connection with the drawings, itwill be readily seen that by connecting the hands together in the mannershown, they may be easily applied or removed or readily adjusted toaccommodate different animals.

A chain, or rope, 13 is attached to the center of the band 1, andconnected at its upper end to the loft, or other suitable supportoverhead, while a second chain or rope, 14, is attached to the center ofthe band 3 for connection with the floor. A chain and ring, 15 and 16,or a strap and roller, as preferred, are suitably connected with theextensions 8 and 9 at each side of the bands, 1 and 3, and are connectedat their outer ends to suitable supports.

By means of the several chains or ropes just described, the horses, orother animals, head may be securely held in any desired position whenusing a dental float or in the course of any dental work, or operationin the mouth or throat, and the work made much easier and greatlyfacilitated.

From the foregoing description taken in connection with the drawings, itis thought that the construction and advantages of this device will bereadily understood with out requiring a more extended explanation.

Various changes in the form, proportions and minor details ofconstruction may be resorted to without departing from the principles,or sacrificing any of the advantages of this invention as defined in theappended claims.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is:

1. A veterinary dental halter, comprising a nasal band, a second bandadapted to fit the lower jaw of the animal, means for adjustablyconnecting the ends of the bands together and resilient means tending toseparate, or spread the bands farther apart.

2. A veterinary dental halter, comprising a nasal band, a second bandadapted to fit the lower jaw of the animal, outwardly bent extensions atopposite ends of the bands, bolts passing through said extensions forconnecting the bands together, thumb nuts screwing on the ends of thebolts,

means for supporting the bands from the animals head and means connectedwith the bands for holding the animals head in the desired position. 3.A Veterinary dental halter, comprising a nasal band, a second handadapted to fitthe lower jaw of the animal, outwardly bent extensions atopposite ends of the bands, bolts passing through said extensions, nutson the threaded ends of the bolts, springs disposed around the boltsbetween 1 the extensions, tending to separate or spread apart thebands,means for supporting the bands from the animals head and meansconnected with the bands for holding the animals head in the desiredposition.

In testimony whereof I affix my signa' ture in presence of twoWitnesses.
